摘要: 玫瑰花Rosa multifrora 'K-2'、Rosa indica 'Major'、Rosa hybrida 'Samantha'、'Landora'之植株，栽培在不同溶氧量之水耕液中，生長在高氧組織水耕液中的植株，枝條的生長速率明顯比中氧組與低氧組植株為快，而地上部枝條之鮮、乾重高氧組亦明顯要較中、低氧組為重。'Landora'植株葉片之光合作用率明顯會因養液中低溶氧量而受到抑制。低氧組植株在高溫下(34℃)，葉片上的氣孔為閉合，而高氧組則為打開。; Plant of Rosa multiflora ‵K-2′、Rosa indica ‵Major′、Rosa hybrida‵Samantha′ and ‵Landora′ were cultured in solutions with different oxygen content. The shoot elongation of rose plants cultured in high oxygen (7-8 ppm) solution was quicker than that cultured in low oxygen (3-4 ppm) solution were also heavier than that cultured in low oxygen. The photosynthesis of ‵Landora′ plant was inhibited when plant cultured in low oxygen solution. There were closing stomata of rose plant cultured in low oxygen solution under high temperature (34℃), when there were opening stomata of rose plant cultured in high oxygen solution.Sun, 01 Jun 1997 00:00:00 GMThttp://hdl.handle.net/11455/815531997-06-01T00:00:00ZA Study on the Emotional Experiences of Five Evergreen Tree Formshttp://hdl.handle.net/11455/81554

摘要: 本研究的主要目的是探討五種常綠喬木造形對於情緒體驗之影響，其藉由本研究之結果尋找出各種不同情緒體驗的植栽配置模式，以提供設計者作為參考之用。本研究應用電腦模擬技術，建構都市公園中之植栽環境及進行五種喬木造型--橢圓形、金字塔形、散形、圓形、紡錘形之模擬，並利用彩色照片與幻燈片進行學者、業者與學生之問卷調查，共取得291份有效問卷。資料分析方法採各種喬木造形主要予人之情緒體驗感受不同，如散形予人平靜舒適之感；圓形予人熱鬧活力之感；紡錘形予人陰沈不安之感；金字塔形予人莊嚴獨特之感；橢圓形則各種情緒體驗之程度均相似。; The main purpose of this study was to investigate the emotional experiences of five evergreen tree forms. It was expected that this study would get different emotional experiences of planting design models and provide the designers with future planting design guidelines. The study applied computer simulation technology (3D Studio) to construct five tree forms, oval, pyramidal, spreading, fastigate and round on the urban park landscape. The five tree forms were turned into color photographs and color slides and students, the study obtained 291 valid samples. The data were analyxed by factor analysis, one-way analysis of variance and T-test. The results indicated different tree forms gave respondents major different emotional experiences for examples, spreading-〝serene-comfortable〞, round-〝animated-alive〞, fastigate-〝dreary-insecure〞, Pyramidal-〝solemn-unique〞.Sun, 01 Jun 1997 00:00:00 GMThttp://hdl.handle.net/11455/815541997-06-01T00:00:00ZMorphological Traits and Cluster Analysis of The Major Introduction Bermudagrass Cultivars in Taiwanhttp://hdl.handle.net/11455/81551

摘要: The introduced bermudagrass cultivars were used as material in the study, the goals for this experiment are to build up a database for bermudagrass morphological characters, and use the data for cluster analysis to construct relationship data between cultivars.
The morphological traits were measured based on the categories for Gramineae grasses. Both qualitative and quantitative characters including: lingual, hairs on the edges of collar, pubescence on leaf blade and on leaf back, stem color, plant height, texture of the leaf and the canopy of the grass were used to describe then added up with the quantitative characters for similarity cluster analysis. With the cluster analysis, 16 bermudagrass cultivars were separated into three groups: common (＞25 cm), dwarf (＜15cm), or semi-dwarf (15~25cm).
There were difficult responses for environment change in each type of bermudagrass in long growing period. Both dwarf and semi-dwarf types bermudagrass grouting is more regularity than common type bermudagrass.
Both quantitative and quantitative morphological traits used for cluster analysis, 16 cultivars were easily categorized into three types groups, the result just correspond with height trait. But only N1 and Tiway can be distinguished by morphological features in all group, others cultivars can not be distinguished individually.; 本試驗以引進品種的百慕達草(Cynodon dactylon)為材料，其目的在建立百慕達草的外觀性狀以及使用連鎖群分析來鑑別栽培種親緣。
百慕達各個品種的性狀調查，參考禾草類的分類標準，根據外部的葉耳、葉舌；葉領邊緣纖毛、葉面及葉背茸毛以及莖的顏色、株型大小、莖葉質地和高度等性狀，建立16種百慕達草品種外觀性狀的詳細資料；由性狀連鎖群分析可將所有品種分為三型，及普通型(25㎝以上)、半矮生型(15~25㎝)及矮生型(25㎝以下)。
各型百慕達草在長時間的生長調查中，對環境變化有不同的反應，以矮生型及半矮生型的品種內及品種間整齊度較為一致，而普通型百慕達草，在品種間及品種內的生長都不整齊。
以性狀外觀資料，加上長時間測量的莖葉長度、寬度值，進行性狀的連鎖群分析，可將所有百慕達草品種區分為三個彼此有差異的性狀連鎖群，此一分群，與百慕達草的高度性狀有明顯的符合。但群內只有N1及Tifway品種能由外觀分辨，而其餘品種，都無明顯的外觀特徵可資辨別。Sun, 01 Jun 1997 00:00:00 GMThttp://hdl.handle.net/11455/815511997-06-01T00:00:00Z乳羅黛粉葉初代培養之研究http://hdl.handle.net/11455/81552

摘要: 乳羅黛粉葉(Dieffenbachia maculata Schott (Lodd.) G. Don. 'Rudolph Roehrs')之葉片培殖體以0.5%或1.0%次氯酸鈉消毒5，10或15分鐘，可使其污染率在15.9%以下，並維持良好癒傷組織生長率。汙染率隨消毒時間而降，但與消毒液濃度無關。次氯酸鈉1.0%消毒15分鐘將使培植體褐化率增加。
老葉培殖體其污染率及褐化率較剛展開或未展開葉高，且癒傷組織生長不良。剛展開葉的不含主脈部份具最佳分生能力。同一葉片的靠近葉柄部份之含主脈培殖體最易污染；而培養基部的葉身培殖體時，癒傷組織的生長最佳。含主脈的培殖體亦遭污染且癒傷組織生長不良，葉身與含側脈的培殖體表現相似。; The contamination percentage of Dieffenbachia maculata Schott (Lodd.) G. Don. 'Rudolph Roehrs' young and soft just expending leaf discs was under 15.9% if sterillized by NaOCl 0.5% or 1.0% for 5,10 or 15 minutes. And was increased with the sterillized time decreased, but there was no related to the concentration. The browning rate was increased by NaOCl 1.0% for 15 minutes.
The contamination and browning rate of mature leaf explants were higher than standard or young leaves but less on callus growth. Lamina of just expending leaf had the best meristematic ability. The explant with main vein near petiole in the same leaf was easy to be infected. Callus growth was the best of lamina approached leaf base. and the explant with main vein was less. The leaf discs with lateral vein responded resembling to lamina.Sun, 01 Jun 1997 00:00:00 GMThttp://hdl.handle.net/11455/815521997-06-01T00:00:00Z
